Specification of Letters Patent. Patented N 16, 192() Application filed November 28, 1919. Serial No. 341,277.

' bending machine,

of Flg. 2,

Fig. 5 is a section on the line 55 of Fig. 1,

Fig. 6 is a perspective detail of the deflector,

Fig. 7 is a perspective view ofa plece of armor before being bent, and

Fig. 8 is a similar view of a piece of tlre armor after being bent.

I have illustrated an embodiment of my invention in a machine having a frame 10 in which is journaled a shaft 11. A pulley 12 is keyed to this shaft while the pulley 13 is journaled thereon. A gear 14 secured to this shaft is meshed with a gear 15 on the shaft 16, which is also journaled in the main frame and which lies parallel to the shaft 11. Each of the shafts 11 and 16 overhang the main frame and have keyed thereto roughened and smoothed rolls 17 and 18, respectively. A deflector 19 carried by a plate 20 is adjustably secured beneath these rolls and a little to one side. This deflector, as shown in Fi 6, has upon its upper face two curved surfaces 19 and 19" The former has substantially the same curve as the roll 18, while the latter lies beneath the opening between the two rolls. At the side of the plate 20 and beneath the roll 17 is placed another adjusting plate 21 which carries a pin 22 upon which is journaled an idler roll 23. The plates 20 and 21 lie in grooves in the face of the main frame, and are secured by means of cap-screws 24 and 25, respectively, and are adjusted by means face curved surfaces one of of screws 26 and 27 which are held by locknuts 28.

The operation of my armor bending machine is as follows: The shaft 11 is driven by a belt (not shown) which may be caused to run on either the tight or loose pulleys 11 and 12. When it is desired to start the machine the belt is shifted to the tight pulley 12 which drives the shafts 11 and 16 in reverse directions. V

Tempered steel plates 29 are fed endwise to the upper side of the rolls 17 and 18. Ow-

ing to the roughening of the roll 17, the plate is drawn down between the rolls and forced against the face 19 of the deflector.

As the armor plate passes the deflector, it comes in contact with the idler roll 23. The deflector 19 and the idler 23 are so adjusted that they bent plate 29.

Templets of the desired curvatures are provided and theplates are bent and tested by these templets, and the deflector and idler adjusted until the desired curvature is provided. By adjusting these two elements different curvature of the plates may be obtained.

WVhile I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope ofthe appended claims in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I claim as new and desire to secure by Letters Patent is: V

1. In a bending machine, a pair of adjacent rolls, a deflector on the delivery side of said rolls comprising a slotted vertically extending plate and an arm integral therewith and extending at substantially a right angle thereto, said arm having on its upper which conforms substantially to the curvature of one of the rolls and the other of which lies beneath the opening between the rolls, and means for adjustably supporting said deflector with relationto said rolls.

2. In a bending machine, a pair of adjagive the desired curvature to the cent rolls, a deflector on the delivery side of and the other of which lies beneath the opensaid rolls comprising a slotted vertically exing between the rolls, means for adjustably tending plate'and an arm integral therewith supporting said deflector With relation to 10 and extending at substantially a right angle said rolls, and an adjustable roller at one thereto, said arm having on itsupper face side of said deflector.

curved surfaces one of which conforms sub stantially to the curvature ofone ofthe rolls "WILLIAM F. RAY.
